Part Number: INA303 Greetings,
I plan to use the INA303A1 in an AFE design. Since its common-mode voltage rating is 36 V and my application requires sensing across a 72 V range, is it possible to leave the shunt resistor floating (not tied to the AFE…
Part Number: INA303-Q1 Other Parts Discussed in Thread: INA303 Tool/software: Dear Texas Instruments Support Team,
I am using the INA303 as a window comparator in a BMS application to monitor current sensing and short-circuit detection.
We are facing…
Part Number: INA303 Other Parts Discussed in Thread: OPA835 , , DRV8311 , INA301 , INA181 Tool/software: I'm trying to muddle my way through my first design with a motor driver that includes current sensing. This is for a battery-powered device, operating…
Tool/software: Dear TI Support Team,
Could you please provide the SPICE model for INA303A2QPW*Q1 Our project requires it for accurate simulation.
Thank you.
Best regards,

Part Number: INA303 Tool/software: Hi team,
In the below sch, let the IN+ and IN- floating (remove R76 and R80), there will be a 1.8V voltage to GND be measured by multimeter on these 2 Pins, that is, measured on the left side of R76 and the left side…
Part Number: INA303-Q1 Tool/software: Hi Expert,
Regarding to the delay function of second comparator, I don't quite follow how delay work.
For example, the delay time is set to 2ms, Vlimit2 is about 3.5V. If there have a 4V/1.5ms voltage pulse on…
Part Number: INA303
We used VREF = 0, VS = 3.3 V, VIN+ = 24 V, ILIMIT1 = 600mA, and ILIMIT2 = 90mA, as our design constraints. Hence we provided RLIMIT1=3K and RLIMIT2= 470R.During our testing, the hysteresis of comparator 2 is observed to be around…
Part Number: INA303 Other Parts Discussed in Thread: INA138 1、It mainly does DC sampling, the front stage is a sampling resistor, and then detected by INA303, but the common mode voltage of INA303 is a little small, only 36V, the common mode voltage of…
Part Number: INA303 Hi everybody,
I would like to verify with you if it is possible or not to set LIMIT1 below LIMIT2 in an INA303Ax. It do not seems forbidden regarding the output comparators which seems quitte independent but I want to be sure it…
Part Number: INA303 Other Parts Discussed in Thread: DRV8313 , , INA301 , INA381 Using 4x INA303 together with DRV8313 (basically the TI reference design) for current sensing a BLDC.
I need the INA's to be considerably smaller.
Please help propose…
